COMBINED TYPE-WRITING AND Application filed March 17, 1913.

To all whom it may concern:

Be it known that I, GUSTAVE O. DEGENEK, a citizen of the United States, residin in New York city, in the county of New lork and State of New York, have invented; certain new and useful Improvements in Combined Type-W'riting and Computing ,Ma chines, of which the following is a specification. Q

This intention relates to combined typewriting and computiu n'iachines, particularly those which are adapted todo computing' in a number of difl'erent coluir ns.

As herein illustrated. this invention is applied to a combined typewriting. and. computing machine of the Underwood-.Vright type, in which the carriage of the typewriter carries a platen on which the writing sheet is placed. This platen, as in: an ordinary typewriter. has a. letter-feedmg motion and is arranged in said motion to control the s-wa r/fim connection betweenv the. numeral keys of the typewriter and the computing wheels of the computing mechanism proper.

For this purpose in said combined ma- ('hine the computing wheels are mounted in a totalizer. and the master-Wheel. is con net-ted to said carriage to be moved thereby so as to engage the computing Wheels in said totalizer serz'atz'm. For computing in several columns or zones tabulator stops may he provided'which are arranged to automatically establish and let go said connection between the typewriter carriage and the master wheel in the totalizer. Thisenables writing done on a work-sheetin several dif 'ferent columns to be computed in onetotalizer as thoughit were Ina single column.

This connection between the tabulator stops and the master wheel may he, inadebyathook adjacent the-typewriter carriage, and. erery time the typewriter carriage'carries a stop past said hook. it automatieallv catohes'thc hook by means of the stop and thereby causes said master wheel to be lllflted by the hook. for predetermined distances A: cam on the hook may be arranged t ride under a stud and torresaid hookfree of said stop when beyond every computing zone.

. The present invention is illustrated asap: plied to a computing machine having a plurality of .totahzors separately counectihle to the numeral keys. For the purpose of varyconronarron ormw YORK. comrorme MACHINE.

Patented July 2, 1918. Serial No. 754,709.

ing the nature of the connections between the numeral keys and the computing wheels, the stops may be'pl'ovided with projections, which, in the travel of the typewriter carriage, are arranged to shift a. clutch or clutches in the gearing between said wheels and said keys. Each of these clutches, for exam Is, in one position may cause the master W eel to rotate the computing wheels so that they add, in another. position may rotate them so that they subtract, or the clutch may be absolutely neutral, as the case may require. he stops may control each clutch. separately by means of cam arms huntgl in the typewriter frame, which arms are rawn by springs to engage said stops as the stops travel with the typewriter carriage.

Ea h totaliz er has an individual convert ing mechanism. and there is no liability of one converting mechanism controlling? the totalizer which belongs to theother conrertmg mechanism, since neither master wheel an UnderWo0d-lVr1ght typewriting and computing machine, ap ,lied thereto. V

were

Said platen is mounted in a carriage 8, trai 'eling on rails 9 and 10, and said carriage is drawn forward in letter-feeding direction by means of a spring barrel 11, and is controlled in said letter-feed by means of an esapement wheel 12, carrying a ratchet wheel 13 which works in a rack 14 mounted on the carriage. Said escapement wheel is controlled by means of dogs 15 and 16, which logs are operated by an extension 17 of a universal member 18, which universal member is operated by heels 19 on the type bars as they rise toward the platen.

Each numeral key as it is depressed arranged to operate the valuating or indexing mechanism escapement, so as to cause the numbers written to be carried into the computing wheels. For this purpose each numeral key is engaged by a link 20 depending from a bell crank 21, which hell crank is joined by a link 22 to the computing mechanism proper. When the key 1 is depressed, it draws link 22, so as to cause the lever 23 to thrust forward a digit-determining jack 24 and sets a pin 25 of a valuating or index wheel 26. At the same time a universal disk 27 is drawn backward by the'head of said link 22, so that the lever 28 rocks the link 29 controlling a secondary escapement, and said secondary escapement comprises a star wheel 30, which has been holdi'ngthe escapement wheel 26 against revolving b means of a pin 25 thereon, which had een previously projected.

The wheel 26 constantly tends to be turned by a motor 31 through a friction slip clutch, not shown, bevel gears 32, 33. and a shaft 34, which .haft has fast to it a bevel gear 35, meshing with a bevel gear 36; and said bevel gear 36 is fast on a shaft carrying a gear wheel 37, which in turn meshes with a gear wheel 38 fast to the index or valuating wheel 26. As the link 29 is moved forwardat the depression of the key, it allows an escapement tooth 39 fast on the shaft/of star-wheel 30 to escape past. a dog 40, so that it strikes a dog 41. and on the return stroke of said numeral key. said tooth 39 escapes from the dog 41 and allows the wheel 26 to carry around its pin 25 which has been hearing against the starwheel 30. so that said wheel 26 can turn until the tooth 25, which has just been pro jected by. the jack 24, strikes the succeeding tooth of the star wheel 30. Said wheel 26 is then held against revolution by means of a second tooth 39, which has been brought around to bear against the dog 40 when the pin 25 strikes the tooth of the star wheel 30.

As; the motor 31 turns said wheel 26. it turns the bevel gear 42, which is constantly in mesh with t e bevel gear 36, and will. through shaft 43, turn the vertical shaft 44 of bevel gears 45 and 46, and in so doing will cause the number then written to be carried into a totalizer 47. The pro jected pin 25, which has been previously engaging the star wheel 30, is returned by a cam wi er, not shown herein, after it passes sai wheel.

In the machine herein shown, there are two totalizers 47, which may be identical and the description of one will answer for both. In each of said totalizers 47 there is a series of computing wheels 48, which are arranged to be engaged seriavtim by means of a master wheel 49 lying within said computing wheels and arranged to be carried back and forth within said wheels to engage them sem'atim in a manner presently who described.

When engaged with any computing wheel 48, said master wheel is arranged to be turned b means of a square shaft 50 on which it is slidably mounted, and said shaft extends through the frame of the machine at 51 where there is fast on it a bevel gear 52, which is arranged to mesh with bevel gears 53 and 54 on shaft 44, and to be turned by one of them in a manner to be hereinafter described. Said master wheel, as will be seen, comprises a hub 55, which is freely revoluble in a sleeve 56, which sleeve, however, moves said master wheel successively into engagement with the various computing wheels. For so moving it, there is pro vided on the carriage 8 of the ty ewriter a rack bar 57 carrying settahle lugs 58, which lugs are arranged to successively engage, as seen in Fig. 5, a hook 59 comprising a notch 60 in which said lugs rest when moving it.

Said book 59 is formed as the end of a sliding rod 61 in the casing 62 fast on the typewriting machine. Projecting downwardly from said rod through a slot 63 in the casing, is a. in 64 engaging one arm of a lever 65, whi h is pivoted at 66, vof which lever the two opposite arms 67 and 68 engage carriages 69, of which carriages the sleeves 56 controlling the scrim Em engagement of the master wheels form a part; lhis lever 65. as from the rear and above in Fig. 4. is normally right by meagis of a spring 70 anchored in the frame ofthe machine. and in such position causes the-'master wheels 49 to engage lhe'highest wheel in each of said totalizers. From such position it is drawn by means of the hook 59. as above described. so that at each letter-space movement of the typewriterit moves the master wheels to engage step by step with the various computing wheels.v

When said hook 59 has drawn the master wheels so that they engage with the units computing wheels. the cam end 71 of the bank is caused to release said hook from the stop 55' by striking a pin 72 fast on the drawn to the frame of the machine, under which pinlsaid hook is drawn until swings dbwn ardclear of the stop 58, and then is drawn bac'lo ward to the highest computing wheelby: the spring 70. Smdhook 59 is held upwardin position where the next stop 58 will strike it by means of a spring 73 bcarin against a screw 74 entered in a socket in t e frame of the typewriting machine.

The lever 65 is slotted at each endwhere it engages the pins 64 and Tithe latter pin being the means by which it is connected to the carriage 69. which causes the step-bystep movement of the master wheel. Said carriage 69 co1n )rises. in addition to the sleeve 56. a sleeve 76. which embraces a rod 77 fast on the frame of the typewrit'ingmachine and carrying in its opposite end a I cross rod 78. which cross rod also supports the outer end of a rod 79, said rod 79 embraced by the plate 80 forming the union between the sleeves 56 and T6 of the master wheel carriage. 7

hen returning the carriage 8 to begin a new line of writing. if the hook 59 is in engagement with one of the stops it carried to the left in Fig. 5 until the cam edge 81 thereon strikes a stud or roller 82'. which may be pivoted on a screw 83 threaded into the top of the boss 84 on which the screw 83 is mounted, and by means of said roller, the hook is cammed downwardly and released from the stop 58. The spring 73 immediately raises the hook. and the stops 58 in succession ride freely over a bevel or point 85 on the tip of the hook. the last stop in the series being caught and held by the hook when the carriage begins to run in letterfeeding direction.

The totalizer +7 comprises a casing 86, through a sight opening 87 in which numerals of the dial wheels 88 may be read. Each dial wheel is constantly in mesh with its computing wheel 48. and said computing wheel carries internal teeth 90. 1%; seen in Fig. 3, arranged to be engaged by the teeth 9i of the master wheel 49. Each com etin wheel also is constantly in mesh with a carry-over wheel 9'2 comprising thfee difier out forms of teeth. Of t iese fr H ofteeth, one set 93 constantly meshes wi 1 i theteeth of the computing wheel 4S, so as to turn said wheel when the carry-over wheel is turned one unils space by the computing wheel next lower in denomination. l lac'h computing wheel also comprises a special tooth. not shown herein. which is arranged to strike a tooth 94 on the carry-over wheel geared to the computing wheel next higher in denounnation. and give that carryover wheel a slight turn when the Zero of the dial wheel turns to the sight opening 87. In giving said wheel this slight turn. it moves it so that teeth 95 of the third form on said com puting wheel engage resilient roll 96 which is power-driven, and said roll completes the turning of the carry-over wheel its one unit space. V aid. resilient roll 96 is driven by a gear wheel 97 meshing with a gear fast on it. which gear wheel in turn is driven by a pinion 98 fast on its shaft and said pinion is driven by a gear wheel 99 fast on. a shaft 100, which is geared to the motor through a bevel gear 101, as will be presently described.

H has been stated that the wheels in tl1e totalizer may be turnedeitlwr to add or snb tract. and for this purpose on the shaft H which drives said wheels. as described above, there is formed a clutch 1 02 for each totalizer. comprising a member 103 slidably splined on said shaft and arranged to lock internally with either the upper bevel gears 54: or the lower bevel gears which bevel gears turn loose on said shaft. The member 103. for this purpose. may be shifted by means of a handle 104 pivoted at 1.05. and on the rearward extension of said handle is formed a series of notches 106 arranged to engage a detent 107 and hold said clutch member in whatever position it may be placed. \Vhen in its upper position. as seen at the top of Fig. 1. it will drive said wheels to add. as shown in the present instance. lVhen said detent holds said handle 10% in its intermediate position. the clutch will likewise occupy an intermediate position. and the shaft ll will turn without af footing the corresponding computing head or totalizer. W ith a handle or lever 10-1: in its lowermost position. the associated clutch 103 will be shifted to drive the corresponding mastcr wheel in a reverse direction. so that a subtracting operation will be performed. That is to say, with the lever or handle IOl in this latter position. a digit run up into the associated computing head will be subtracted from any number accu' mulated. therein. v

For enabling thepower-driven resilient roll 96 of the carry-over mechanism to be reversed sin'iultaneously with the reversal of the master wheels. a set of clutches is provided for the carry-over mechanism similar to those provided for the master wheel shafts comprising shiftable members 10S. which are operated by extensions of the handles 104. extending beyond the pivots 105. so as to shift said members 108 sinniltancously with the shifting of the members 103 for the master wheels. Said members 108 are slidibly spliucd on a shaft 109. which is driven from the motor by means of a bevel gear 110 fast on said shaft 109. a bevel gear ill meshing therewith. which bevel gear fast on a shaft 11?. carrying a bevel gear 113 meshing with a bevel gear 11-! fast on shaft 34.

The lugs 58. which have been above described as connecting the master wheel to the typewriter carriage so that they have a similar step-by-step movement, are preferably formed as extensions of tabulating stops 115 also mounted on a rack bar 57. Said tabulating stops are arranged to co'ciperate with key-operated plunger stops 116 of the usual Underwood type, operated from keys 117 at the front of the keyboard, mounted on levers 118, pivoted at 119, which levers carry said plunger stops at their rear ends 120. Each of said tabi'ilator keys is arranged, when it is operated, to release said typewriter carriage 8 from the escapement mechanism in the usual manner. The connections for accomplishing said release include a universal bar 121 operated by heels 122 on the stop plungers 116, and said universal bar is fast on a rock shaft 123 carrying a rock arm 124, which through a link 125 draws down the rear end of a lever 126. so as to swing the front end thereof upward and cause an idle wheel 127 thereon to lift the rack 14 out of the ratchet wheel 13. When the carriage is thus released from its escape ment wheel 12, it is drawn forward in letterfeeding direction until the stop plunger 116 arrests it by intercepting a carriage stop 115. Said plunger stops 116 form a decimal tabulator inclosed in a casing 128.

The carriage stops 115, in addition to the lugs or extensions 58, also include projections 129, 130 and 131. Said projections are of varying depth and are arranged to automatically shift the clutches 102, which control the turning of the computing wheels by means of the numeral keys, thus relieving the operator of the necessity of manually shifting the handles 104. For this purpose there is journaled on the casing 128 a shaft 132 carrying a rock arm 133, which rock arm is arranged to coiiperate with the upper end of one of the stops 115. When said rock arm 133 is held inward, as seen in Fig. 1, it rocks an arm 134 fast on said shaft 132, so as to move a forwardly extending link'135 pivoted on said rock arm to swing a bell crank 136 rearwardly, so that the arm 137 thereof, which is pivoted in a slot 138 on an exten sion of the handle 104, will shift said handle into its downward position at the forward end and cause said clutch to connect the master wheel to subtract. In the same way the lower end of the stop 115 is arranged to swing arm 139 fast on a sleeve 140 on said shaft 132, and thereby swing arm 141 fast on said sleeve to draw an upper link 142, so as to cause its bell crank 143 to swing its extension 144 to swing the upper handle 104 upwardly, and thus cause said handle to add.

It will be observed that the rock arms 134 and 141 extend in opposite directions, and to offset this, the bell cranks 136 and 143 are set to work in opposite directions, so that identical lugs of the stops 115 will have identical effect on both rock arm 133 and rock area 139. Each of said rock arms 133 and 139 is drawn by a spring 145 in a forward direction constantly tending to move it to cause the computing mechanism to subtract.

In order to enable the typewriter carriage to feed past the fiat faces 146 and 147 of rock arms 133 and 139 respectively, the ends thereof are beveled as at 148 to form cam surfaces which will force said arms out wardly when the stops strike them. Each of the rock arms 133 and 139 is formed where it is fast onto its shaft or sleeve respectively comparatively narrow, so that the two portions thereof where fast to their shaft and sleeve will not take up more than the column over which they are arranged to effect the computing mec anism. The rock arin 139 is formed with a narrow portion 149 and then at the top is extended broadly so that the edge 147 is of substantial length. The rock arm 133 is formed with a narrow portion 150, which then extends to the right and then upwardly at 151, and then to the left at 152, so that the edge 146 will be of precisely the same length as edge 147, and precisely above it. In this way the two rock arms 133 and 139 swing preferably clear of each other, and operate on the same column. The rock arm 133 in its narrow portion is bent outwardly at 153, so that the narrower portions 149 and 150 near their tops will lie in the same plane when not engaging in steps 115.

The stops 115 may include any desired combination of adding, subtracting and neutral positions, such as are shown in Fig. 9. The rock arms 133 and 139 are locked to their carrying members by means of set screws 157 and 158, so that they may be ad usted thereon.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
